Canon SX400 IS vs Casio EX-H20G: A Detailed Hands-On Comparison for Enthusiasts and Professionals

Choosing the right compact camera with superzoom capabilities can be challenging, especially when models target slightly overlapping user needs but differ substantially in features, handling, and image quality. Today, I’m diving deeply into two popular small sensor compacts from the mid-2010s: the Canon PowerShot SX400 IS and the Casio Exilim EX-H20G. Both cameras offer versatile zoom ranges and approachable designs but cater to different photography styles and expectations.

Having personally tested thousands of cameras over the years - including both models extensively - I’ll unpack the strengths, limitations, and real-world performance differences you should consider before investing. By the end, whether you’re a casual snapshooter, an enthusiast eager to explore zoom photography, or a professional looking for a capable travel companion, you’ll know which model fits your needs best.

First Impressions: Size, Ergonomics, and Handling

One of the first notable differences I observed is the physical size and build quality. Both cameras belong in the compact category, but they differ noticeably in dimensions and grip comfort.

• Canon SX400 IS: Slightly bulkier at 104 x 69 x 80 mm and weighing 313 grams, the SX400 IS feels robust and offers a decent handgrip considering its compact nature. The deeper lens barrel contributes to its heft, but this also translates to stability when shooting at full zoom.

• Casio EX-H20G: At 103 x 68 x 29 mm and just 216 grams, the Casio is significantly slimmer and lighter. Its thinner profile makes it more pocket-friendly, though this comes at the expense of a less pronounced grip and thus potentially less stability during extended shooting sessions.

Neither camera features weather sealing, so both require care in adverse conditions.

User Interface and Control Layout

The top-control designs warrant attention, as intuitive handling can make or break your shooting experience.

• Canon packs the SX400 IS with straightforward buttons and a traditional mode dial, although options like manual exposure are absent. The zoom toggle is conveniently placed; however, the lack of dedicated manual focus controls limits creative control.

• Casio’s EX-H20G foregoes a mode dial but includes manual focus rings - that's a plus if you want greater control - but compensates with fewer physical buttons, relying more on on-screen menus. It also offers GPS functionality, an uncommon feature in this class, making it attractive for travel photography.

Sensor and Image Quality: What the Specs Tell Us

Both cameras rely on a 1/2.3” CCD sensor of 28.07 mm² area, but there are subtle differences that impact final image quality.

• Resolution: The Canon offers 16 MP, slight bump over Casio’s 14 MP. While more pixels can mean better sharpness, it can also introduce noise if sensor technology isn’t optimal.

• ISO Range: Canon’s maximum ISO 1600 is relatively modest compared to Casio’s extended ISO up to 3200 with a lower minimum ISO 64, giving Casio a theoretical edge in both low-light and well-lit scenarios.

• Sensor Noise and Dynamic Range: Unfortunately, neither camera has been extensively benchmarked by DxOMark. From my hands-on shooting, both produce adequate images in bright daylight but struggle at higher ISOs, typical of smaller CCD sensors. Casio’s sensor shift image stabilization slightly helps with sharpness at slower shutter speeds.

Overall, you should expect respectable image quality for casual use but not the richness or flexibility of larger sensor cameras, especially in challenging light.

LCD Screens and Viewfinders: Composing Your Shots

Both cameras lack viewfinders and rely on their rear LCD screens exclusively.

• The Casio features a sharper 3” screen at 461k dots, nearly double Canon’s 230k dots. This difference translates to clearer previews, making frame composition and focus verification easier on the Casio.

• Neither display supports touch input or articulates for unconventional angles, limiting shooting flexibility somewhat.

For photographers shooting outdoors or in bright light, Casio’s brighter and higher-resolution screen is more comfortable, but neither camera offers an electronic viewfinder - a notable omission for serious outdoor or telephoto shooters who need stability and precision.

Zoom Ranges and Lens Characteristics: Reach vs. Aperture

Zoom versatility is a staple feature here, yet the cameras approach it differently.

• Canon SX400 IS: Offers an impressive 30x optical zoom spanning an equivalent focal range of 24mm wide to 720mm telephoto. This makes it ideal for wildlife and sports enthusiasts needing extended reach without carrying extra lenses.

• Casio EX-H20G: With a 10x zoom covering 24-240mm equivalent, it leans towards wide-to-telephoto versatility but with less reach, favoring travel and street photography where size and weight matter.

Lens Brightness

• Canon’s maximum aperture varies from f/3.4 wide to f/5.8 telephoto - relatively standard for superzoom compacts - but the slower aperture at the long end limits low-light telephoto usability.

• Casio’s f/3.2 to f/5.7 aperture is slightly faster, especially wide open, and the sensor-shift stabilization helps keep images sharp at longer exposures.

Autofocus Systems and Performance: Speed & Accuracy

Autofocus systems are critical, especially for wildlife, sports, and street photography.

• Canon SX400 IS: Employs contrast-detection AF with nine focus points and supports face detection. It also offers continuous AF and tracking modes, allowing better subject tracking in dynamic scenes - a valuable asset when shooting moving subjects.

• Casio EX-H20G: Uses a simpler single-point contrast-detection AF system without face detection and lacks AF tracking, which could frustrate in fast-action environments.

My tests showed Canon’s AF to be more reliable and quicker locking onto subjects, particularly when zoomed in. Casio’s autofocus occasionally hunts, especially in low contrast or low-light conditions.

Burst Shooting and Shutter Speeds: Capturing Action

Neither model is sports photography powerhouse, but they differ in burst capabilities.

• Canon’s burst shooting is limited to around 1 fps, making it slow for capturing rapid sequences.

• Casio’s burst mode specifications aren’t stated, but responsiveness is limited in practice. Maximum shutter speeds favor Canon (up to 1/1600s) versus Casio’s 1/2000s, theoretically better at freezing action; however, slower buffer clearing hampers continuous action capture.

For sports or wildlife shooting, the SX400 IS’s modest burst speed paired with longer zoom still gives it an edge in telephoto reach and subject tracking.

Video Capabilities: Recording Features and Quality

Both cameras support HD video at 720p resolution, but there are subtle differences worth noting.

• Canon SX400 IS: Records 1280x720 at 25 fps, offering MPEG-4 and H.264 formats. It lacks microphone or headphone jacks, and no built-in stabilization for video beyond optical IS.

• Casio EX-H20G: Also delivers 720p video, but at 30 fps, and incorporates sensor-shift stabilization which smoother results. It features HDMI output for easy connection to TVs and supports Eye-Fi wireless memory cards for wireless transfer - a nice perk.

Neither camera competes with modern video-focused models, but if casual HD video is on your agenda, Casio’s stabilization and HDMI out may edge out the Canon.

Battery Life and Storage Flexibility

• Canon uses the NB-11LH battery rated for approximately 190 shots per charge.

• Casio’s NP-90 battery life isn’t manufacturer rated clearly, but in my testing, it performs comparably to Canon, lasting several hundred images under mixed use.

Both cameras take SD/SDHC/SDXC cards with single slots only - standard in their class.

Connectivity and Extras: What More Do You Get?

• Casio EX-H20G: Includes built-in GPS for geotagging your photos - a bonus for travellers wanting to track their adventures. It also supports Eye-Fi wireless connectivity for image transfer.

• Canon SX400 IS: Offers none of these wireless capabilities, which is a limitation in today’s connected world.

Neither camera offers Bluetooth, NFC, or Wi-Fi, reflecting their release dates.
